JAMES WILLIAM DEOKERT, OF OAKVILLE, CANADA.

SETTING-OUT, GLASSING, AND POLISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 789,262, dated May 9,1905.

Application filed October 15, 190 Serial No. 228,642.

To all whom, it may concern:

Be it known that I, J AMES WILLIAM DnoK- ERT, leather-splitter, acitizen of the United States,residing in the town of Oakville, county ofHalton, Province of Ontario, Canada, have invented certain new anduseful Improvements in Setting-Out, Glassing, and Polishing Machines, ofwhich the following is a specification.

My invention relates to improvements in setting-out, glassing, andpolishing machines: and the objects of my invention are, first, toprovide a machine of this class that will adjust itself to the differentthicknesses of the hide, so that thin as well as thick portions thereofwill be thoroughly set out, glassed, or polished; secondly, to regulatethe pressure of the hide againstthecylinder; thirdly,to firmly yetyieldingly keep the hide in contact with as much of the cylinder aspossible, prefer ably one-quarter of the periphery of same, so that thehide may be thoroughly worked upon, and, fourthly, to construct anefiicient machine of this class at the minimum cost; and it broadlyconsists of a rotary cylinder and non-rotatable means constructed so asto keep thin as well as thick portions of the hide in contact with saidcylinder under variable or constant pressure, and details ofconstruction, as hereinafter more particularly explained.

Figure 1 is a front side elevation of my machine. Fig. 2 is a verticalsection on the line a b, Fig. 1. Fig. Sis an enlarged perspective viewof the means used for keeping the hide in contact with the cylinder.Fig. I is a vertical section on the line 0 (Z, Fig. 2. Fig. 5 is anenlarged cross-section through one of the blocks used for keeping thehide in contact with the cylinder. Fig. 6 is a perspective view of thepreferred form of bracket. Fig. 7 is a vertical section on the line aI), Fig. 1, showing my machine assembled for doing heavy work, certainparts being removed.

In the drawings like characters of reference indicate correspondingparts in each figure.

A is the bed of the machine, and C the headblocks, suitably securedthereto. Suitably mounted in these head-blocks is the cylinder D. On oneend of the shaft E of the said cylinder is a drive-pulley F.

G represents suitable tie-girths, by means of which the head-blocks Oare supported at their upper portions.

Althoughl may use any construction of cylinder in connection with mymachine, I preferably use the cylinder described and claimed in myapplication, Serial No. 212,672, filed June 15, 1904:, the patent forwhich is dated October 4, 1904, and numbered 7 71,614.

The shaft E is preferably held in any suitable adjustable bearings H.

In order to get the best possible results in working hides, it isabsolutely necessary that thin as well as thick portions thereof beworked upon. For delicate work, such as glassing or polishing, I firmlyyet yieldingly support in the position shown relative to the cylinder Da series of blocks I, preferably made of rawhide, but which may be madeof any suitable material. The edge of these blocks adjacent thecylinderD is approximately concentric thereto, so that when the hide Jis placed and held between same and the cylinder all portions of thehide held by said blocks will be held under varying pressure in contactwith said cylinder, the pressure being preferably gradually increasedfrom point of first contact of said cylinder with the hide to pointwhere it leaves same. As will be seen from Fig. 2, I preferablyconstruct said blocks so that they will keep the portion of the hideoperated upon case a thick portion of the hide should be held betweenthe cylinder D and any of the blocks I the said blocks and their fingersit will yield sufficiently, and in case a thin portion of the hideshould be held between the cylinder and any of the blocks the fingers Zrwill be caused to exert a force so as to keep the thin portion ICO ofsaid hide in contact with the cylinder by means of their blocks I.

Placed underneath the steel plate K is an intermediate plate L,extending for the whole length of same, but of less width than saidplate, so as not to interfere with the movement of the fingers it, andunderneath the plate L is another steel plate M of equal length to theplate L, but of less width than same. Through the back portions of theseplates and through the upper base-plate N and intermediate base-plate 0pass the screws P, which secure the above-mentioned parts to the lowerbase-plate Q, held by any suitable bearing-caps R upon the pivot-bar S,supported at its ends, as hereinafter described. The intermediatesupports for said pivot-bar preferably consist of stands T, through theupper portion of which said pivot-bar passes. By means of the screws 25the slotted base of the said stands is secured to the bed A. By sosupporting the plates K, L, and M upon each other it will be understoodthat their movement will not be interfered with.

In order to support the fingers k on their under sides and near theirends so that they may maintain the requisite pressure of the blocks Iagainst the hide during polishing or glassing, I provide a resilientfoundation constructed in any suitable manner. My preferred means forthis purpose consists of a rubber cushion U, suitably held by thebrackets V in position upon the intermediate baseplate 0. This resilientfoundation will permit of the necessary movement of the blocks I. Inorder to regulate the pressure of the blocks I against the hide, Isuitably connect the front portion of the lower base-plate Q, with therock-shaft W, suitably held in the head-blocks (J. For this purpose myconstruction shown consists of connecting-rods B, the lower ends ofwhich have bearing upon the eccentrics W, secured to the rock-shaft W.By means of the socket-plate B thereon, having bearing in the lowerbase-plate Q, and the slot (1/ in said lower base-plate saidconnecting-rods may have movement at their upper ends, so that when thearm C, secured to one end of the rock-shaft W, is moved, say, in thedirection indicated by arrow, the eccentrics W" move the connecting rodsB downward, so as to tilt the rear side of the lower base-plate Q, andthus move the fingers and lower portions of the blocks I closer to thecylinder D. By means of any suitable fastening means 0 the arm C issecured to the quadrant C (suitably secured to the machineframe,) andthus the blocks 1 held in the required position. B represents nuts onthe upper end of the connecting-rods B to keep same in position. 7

Then the hide between the blocks I and cylinder D has been sufficientlyworked, the arms C are moved upward, thus releasing the pres sure of theblocks I against the hide, so that the worked portion of the hide may bemoved onto the receiving-board D, held at the required angleupon thebrackets D suitably secured to the bed A. The to-be-worked-upon portionof the hide is moved from the feeding-board D (suitably secured to thebrackets D", in turn suitably secured to the lower baseplate Q) intoposition between the blocks I and cylinder D and the necessary pressuregiven to said blocks.

By means of the screws d, extending through the slotted base of thebrackets D the said brackets are adjustable.

By means of any suitable bearing-blocks A, suitably secured to the bedof the machine, the rock-shaft W is given intermediate hearing.

By means of the arm C, connecting-rods B, and means intermediate sameand the blocks I the pressure of the said blocks against the hide isregulated. This movement throws the upper portion elof the blocks I awayfrom the cylinder. In order to regulate the distance of the upperportion of said blocks from the cylinder, I provide means whereby thelower base-plate Q, and supporting parts are moved. Each end of thepivot-bar Sis held in the sliding plates U, sliding between theguide-strips U suitably secured to the inner side of the head-blocks.Suitably secured to the outer end of the sliding plates U are brackets Uin which have movement the adjusting-screws U, which screw into the edgeof said headblocks. In order to move the blocks I toward the cylinder,the screws t are loosened and the screws U turned so as to move thesliding plate U inward, and thus, through the pivot-bar S and connectedparts, give the said blocks the necessary movement. When the parts arethus adjusted, the screws tare tightened up. v1

The normal position of the blocks I is such that the lower portions ofsame will be closer to the cylinder than the upper portions, thusgradually increasing the pressure of the cylsame first comes in contacttherewith to the point where same leaves the hide.

For heavy work, such as setting out leather, I dispense with the blocksI, feeding-board D and brackets l) and merely use the plate K and itsfingers is. (See Fig. 7.) The fingers Zr: will keep all inequalities inthe thickness of the hide in contact with the cylinder. Of course when Ionly use the fingers it it will be understood that only a small portionof the periphery of the cylinder will be in contact with the hide at anygiven period. By means of the parts before described for moving theblocks I to or from the cylinder it will be understood that the distanceof the tongues to or from the cylinder D will also be regulated thereby.

I preferably support the blocks I so that the hide will be held incontact with the cylinder IIO I inder against the hide from the pointwhere 1 under varying pressure; but I do not confine myself to sosupporting said blocks, as same may be supported so that theirconvex-surfaces will be concentric to said cylinder.

As before mentioned, the blocks I may be made of any suitable material;but I preferably make same up of'a plurality of pieces of rawhide c" andsuitably secure them together, as by rivets The ends 2'" and t" of saidblocks are rounded, so as not to interfere with the movement of thehide.

I do not confine myself to the construction herein shown and described,as same'can be altered in various ways without departing from the spiritof my invention.
